Hi Ken,
You already received great links and content.
What I would also recommend is creating a plan of approach (adoption strategy);
- create a multi-disciplinary team (business, technical) but also have different champions / early adopters to create awareness and take the lead in the adoption process
- create a strategy (i.e. different scenario’s)
- assess readiness and build a plan
- execute and onboard with continuous measurement and improvement
Great adoption course can be found on Edx;
